The first sensation to return to me was a sort of repetition of the asphyxia.  The blood seemed to be forcing itself into my eyes—­I choked —­I felt that my end was come.  And, raising my hands to my throat, I found it to be swollen and inflamed.  Then the floor upon which I lay seemed to be rocking like the deck of a ship, and I glided back again into a place of darkness and forgetfulness.

My second awakening was heralded by a returning sense of smell; for I became conscious of a faint, exquisite perfume.

It brought me to my senses as nothing else could have done, and I sat upright with a hoarse cry.  I could have distinguished that perfume amid a thousand others, could have marked it apart from the rest in a scent bazaar.  For me it had one meaning, and one meaning only—­ Karamaneh.

She was near to me, or had been near to me!

And in the first moments of my awakening, I groped about in the darkness blindly seeking her.

Then my swollen throat and throbbing head, together with my utter inability to move my neck even slightly, reminded me of the facts as they were.  I knew in that bitter moment that Karamaneh was no longer my friend; but, for all her beauty and charm, was the most heartless, the most fiendish creature in the service of Dr. Fu-Manchu.  I groaned aloud in my despair and misery.

Something stirred, near to me in the room, and set my nerves creeping with a new apprehension.  I became fully alive to the possibilities of the darkness.

To my certain knowledge, Dr. Fu-Manchu at this time had been in England for fully three months, which meant that by now he must be equipped with all the instruments of destruction, animate and inanimate, which dread experience had taught me to associate with him.

Now, as I crouched there in that dark apartment listening for a repetition of the sound, I scarcely dared to conjecture what might have occasioned it, but my imagination peopled the place with reptiles which writhed upon the floor, with tarantulas and other deadly insects which crept upon the walls, which might drop upon me from the ceiling at any moment.

Then, since nothing stirred about me, I ventured to move, turning my shoulders, for I was unable to move my aching head; and I looked in the direction from which a faint, very faint, light proceeded.

A regular tapping sound now began to attract my attention, and, having turned about, I perceived that behind me was a broken window, in places patched with brown paper; the corner of one sheet of paper was detached, and the rain trickled down upon it with a rhythmical sound.

In a flash I realized that I lay in the room immediately above the archway; and listening intently, I perceived above the other faint sounds of the night, or thought that I perceived, the hissing of the gas from the extinguished lamp-burner.

Unsteadily I rose to my feet, but found myself swaying like a drunken man.  I reached out for support, stumbling in the direction of the wall.  My foot came in contact with something that lay there, and I pitched forward and fell. . . .
